Hi,

I am developing COM addins for Word and Excel. To work with these office
applications my project has references to the corresponding COM objects
(Microsoft Word 11.0 Object Library, for instance).

Recently I started using a second computer for development. After having
copied my project from computer A to B, Visual Studio on B told me that
it couldn't find some interop assemblies. I could follow this, since the
project folders on A and B are distinct.

When checking locations of the interop assemblies, it turned out that
they were in the GAC on A, but on B they were in local project folders.

Now my questions:
a) why are interop assemblies in the GAC on A, whilst they are in local
project folders on B?

b) How can I develop on differnet computers without updating references
each time I have copied my project from A to B or vice versa?
(please note: having identical root paths on A and B is not the solution
 I am looking for).

Thanx for your answers
Kind regards
Bernd
